genetically distinct uniquely identifiable samples of plant genetic resources within a genebank


in a climate change context, taking action to prepare for and adjust to both the current and projected impacts of climate change

adaptive resource management

a structured, iterative process for improved management practices based on implementing plans that reduce uncertainty and that allow for opportunities to learn from experience


relating to ecological processes applied to agricultural production

carbon sequestration

the capture and storage of atmospheric carbon dioxide

climate system

an interconnected system consisting of five major components: the atmosphere, the hydrosphere, the cryosphere, the land surface, and the biosphere

climate-ready plant collections

plant collections that are resilient to the changing environment, with particular reference to climate-change

crop wild relatives

the wild undomesticated plants most closely related to agricultural crops that potentially possess useful traits/genes/alleles for crop improvement


a crop variety produced by scientific breeding or farmer selection methods

de novo

Latin term meaning “from the beginning”

developmental plasticity

the property by which the same genotype produces distinct physical and physiological characteristics depending on the environmental conditions under which development takes place

ex situ conservation

conservation of plant genetic resources outside their natural habitat

exceptional species

plant species that are threatened or endangered

food system

the network of activities ­connecting people to their food


allelic constitution of an organism at one or more loci

in situ conservation

conserving plant genetic resources on-farm or within ecosystems


transfer of genetic information from one taxon (or parent) to another through hybridization and repeated backcrossing to one of the taxa (or parents)


a local plant variety, usually genetically heterogeneous, with distinctive characteristics arising from selection over time for adaptation to localized conditions or food preferences


in a climate change context, actions that reduce or prevent greenhouse gas emissions or that lower the amount of greenhouse gases in the atmosphere

passport data

basic information about the origin of a genebank accession, such as collecting site or pedigree


cyclic and seasonal aspects of plant growth and development (such as flowering time)


observable characteristic of an organism

plant genetic resources

the organs and tissues (seeds, fruits, cuttings, pollen, tissue cultures, etc.) by which plants can be propagated (synonymous with plant germplasm)

plant genetic resources for food and agriculture

plant genetic resources indispensable for crop genetic improvement essential for meeting current and future human needs

plant germplasm

the organs and tissues (seeds, fruits, cuttings, pollen, tissue cultures, etc.) by which plants can be propagated (synonymous with plant genetic resources)


introgression of desired genes from wild plant species (or crop wild relatives) into breeding lines; enrichment of a breeding population for particular genes and/or traits; and development of novel breeding populations


necessary chilling prior to growth of dormant or quiescent plant materials (such as for seed germination)
